HYDRANT.

Specification of Letters Patent.

Patented March 24, 1908.

Application filed February 5, 1907. Serial No. 355,880.

To all whom it may concern:

Be it known that I, Gums J. Cnms'rENsoN, a citizen of the United States, residing at Kellogg, in the county of Jasper and State of Iowa, have invented new and useful Improvements in Hydrants, of which the following is a specification.

This invention relates to improvements in hydrants, particularly of the lawn-type, the main object of the'invention being to provide a simple, cheap, durable and efficient construction of hydrant in which provision is made to prevent liability of water freezing therein and to permit ready assemblage and disassemblage of the parts, so that the pump may be set up and repairs made in a ready and expeditious manner.

A further object of the invention is to provide means whereby the flow of water from the body or stock will be automatically cut off when the parts of the feed valve mechanism are removed for repairs or replacement.

In the accompanying drawings,-Figure 1 is a vertical longitudinal section through a hydrant constructed in accordance with my invention. Fig. 2 is a detail of the latch. Fig. 3 is a top plan View of the perforated guide plate.

Referring to the drawings, 1 represents hollow or tubular body or stock provided at one sidewith inlet 2 for connection with the The lower end of the stock is closed by a removable head 3 having a threaded engagement therewith, and the upper end of the stock is formed. with a reduced threaded opening 4 and a seat face 5 arranged above the plane of the inlet 2.

A valve casing 6 enters the stock through the threaded opening 4 and is threaded for engagement therewith, the upper end of said casing being suitably coupled to the lower end of a delivery pipe 7 closed at its upper end. by a detachable hollow head 8 provided with a discharge spout 9. The lower end of the valve casing terminates in a chambered portion 10 having a closed bottom 10 and extending into the stock-below the seat 5, said chambered portion being formed in its sides with ports 11 for the entrance of water thereto. An annular flange 12 contracts the valve casing to provide port 13 and a valve seat 14, which latter is preferably beveled for engagement by the correspondingly shaped surface of a feed valve 15, whereby the flow of water from the chamber into the upper portion of the valve casing and thence through the delivery pipe to the hollow head and spout is controlled.

The valve 15 isoarried by a rod 16 extending upwardly through the valve casing and delivery pipe and also through the top wall of the head 8. The lower end of the rod works through a central opening in a guide plate 17 arranged within thevalve casing, which plate is provided with a plurality of apertures 18 for the flow of water therethrough, while the upper end of the rod is threaded to receive a nut 19. An operating lever 20 is fulcrumed at one end, as at 22, to a short standard 23 on the head 8, and is perforated for the passage of the upper end of the rod, and the opposite or free end of said lever is bent or curved to form a handle and bucket supporting portion 24. The lever bears against a shoulder 25 formed or provided on the rod and is held loosely in engagement therewith by the nut 19, so that upon the de pression of said. lever the valve 15 will be opened for the discharge of the water' A coiled spring 26 surrounds the rod between the head and shoulder and serves to return the lever, rod and valve to normal position when the pressure upon the lever is removed. The end 2 1 of the lever is adapted to be engaged by a pivoted rin -latch 27 carried by the nozzle, whereby the lever may be held depressed for the continued discharge of water.

The stock and valve casing may be made of any suitable non-conducting material or protected. in any suitable manner to prevent freezing of the water therein in cold weather, and the casing is preferably provided below the guide 17 with a drain outlet 28 for the discharge of water left remaining in the hydrant above the level of the feed valve.

It will be understood that by reason of the detachable engagement of the parts, the valve casing may be removed from the stock for renewal or repairs of any of its parts. In order to cut off the flow of water through the stock when the valve casing is removed for either of these purposes, a cut-off valve 29 is provided, and has a stem 30 movable in a guide socket 31 carried by the head 3. The valve is adapted to be moved upwardly against the seat 5 to cut off the passage of water through the stock by a coiled spring 30 surrounding the socket between the valve and head 3. The valve is normally held depressed against the resistance of the spring below the inlet 2 by the valve casing, which bears thereon, but upon the disconnection of said casing the spring operates to move the valve upward against the seat 5, thus cutting off the flow of water through the stock, as will be readily understood.

Having thus described the invention, what is claimed as new is1- 1. A hydrant comprising a stock, a delivery pipe communicating therewith, a detachable head closing the upper end of the pipe and provided with a discharge spout, a valve controlling the discharge of water through the stock and into the delivery pipe, a rod connected with the valve and extending upwardly through the head and provided with a shoulder and a threaded portion, a standard upon the rear portion of the head, a lever pivoted at one end to the standard and having a hooked free end overhanging the spout, said lever being provided with an intermediate opening for the upward passage of the threaded end of the rod and resting below said opening on the shoul der, a nut engaging the threaded end of the rod and holding the lever in contact with said shoulder, a spring surrounding the rod between the head and shoulder and serving to return the lever and rod to normal position, and a pivoted latch upon the spout to engage the lever and hold the same depressed in valve-opening position.

2. A hydrant comprising a stock having a side inlet and a contracted opening at the top thereof, the wall of which forms a seat shoulder above the plane of the inlet, a de tachable head closing the bottom of the stock, a valve casing threaded into the contracted opening and having a portion depending into the casing and provided with a closed bottom, side ports, and a constricted upper outlet port and valve seat, an outlet valve arranged in said casing and adapted to engage said seat, an outlet pipe connected with the valve casing and provided with a discharge nozzle, a rod connected with the valve and extending upwardly through the outlet pipe, means for operating the rod, and a spring actuated cut-oil valve supported by the bottom head of the stock and bearing against the closed lower end of the valve casing, said valve being normallyheld depressed by said casing and adapted upon the withdrawal thereof to engage said seat shoulder and cut off the fiow'of water.

3. A hydrant comprising a stock having a side inlet and a detachable bottom head, the latter being provided with a socket, a valve casing detachably fitted in the upper end of the stock and having a chambered portion entering the same, a valve arranged in said chambered portion and controlling the flow of water through the valve casing, a cut-off valve within the stock normally held depressed by the valve casing and having a stem movable in said socket, and a spring operating on the valve to move it to a position above the inlet to cut ofi the flow of water through the stock when the valve casing is removed. e

4. A hydrant comprising a stock having a side inlet, a removable bottom head, and a threaded opening in its top of less diameter than the stock, a valve casing entering the stock through and engaging with the threaded opening and having a port therein and provided below the port with inlet openings, a valve controlling said port, a valve mov ably supported by the bottom head of the stock and normally held depressed by the valve casing, and a spring for operating said valve to close the threaded opening when the valve casing is removed.

5. A hydrant comprising a stock having a side inlet and. a detachable bottom head, said stock being provided at its upper end with a contracted internally threaded opening, the wall of which forms a seat shoulder above the plane of the inlet, a valve casing having a threaded portion engaging said threaded opening, and provided at its lower end with a chambered portion entering the stock and arranged opposite the inlet, the said chambered portion being closed at its lower end and provided with side inlets and having at its upper end an annular flange forming a discharge port and a valve seat, a

valve arranged in said chambered portion and adapted to engage said seat, a rod con nected with the valve and extending upwardly from the outlet port, means for controlling the rod, and a spring actuated cutoff valve supported by the detachable bottom head of the stock and bearing against and normally held depressed by the closed bottom of the chambered portion of the valve casing, said cut-off valve being adapted upon the removal of the valve casing to be forced upward by its spring to engage said seat shoulder and out off the flow of water through the stock.

In testimony whereof, I afliX my signature in presence of two witnesses.
